Article: With more and more wineries   offering organic varieties to lower their eco-footprint  , it's no surprise that they're looking at the environmental impacts of their packaging as well. The making of conventional glass bottles and the corks   uses large quantities of natural resources and causes a lot of pollution. Beyond manufacturing, the transport of wine in glass bottles across the country and around the world also has its environmental effect. Trucking all the heavy glass bottles causes a much larger carbon footprint than the transportation of much lighter boxed wine. Almost half the weight of an ordinary case of wine comes from the bottles; about 95 percent of the weight of a case of boxed wine is the wine itself. "A standard wine bottle holds 750 milliliters of wine and causes about 5.2 pounds of carbon dioxide when it travels from a farm in California to a store in New York," reports Colman, a researcher. "A 3-liter box causes about half the carbon dioxide per 750 milliliters." According to the Wine Group, the third largest wine company in the world and a big advocate for switching away from glass bottles, there are other advantages to boxed wine (which typically includes a plastic bag within a cardboard box). The vacuum   packaging of boxed wine allows it to stay fresh for up to six weeks in the fridge once the seal is broken and the first glass has been poured. Still, despite the benefits, boxed wine may still be a tough pill to swallow for many wine experts. "Even those traditionalists who are coming around to the idea that maybe screw caps   are fine for some wines, would not like the idea of a cellar   full of cardboard boxes," says wine writer Lee Asbell. "It is difficult to imagine how wine service at fine-dining establishments would handle such a change." For now, boxed wine is still the field of cheaper brands. But that could all change as more and more wine makers and drinkers take responsibility for saving the Earth. 
 Question: Compared with glass bottled wine, boxed wine   _  . 
 Options: (A) wastes more natural resources (B) is difficult to transport (C) causes less eco-footprint (D) takes up more space 
 Asnwer: B
No

Article: A lot of people these days believe Valentine's Day is a made-up holiday designed to promote the sale of greeting cards and gifts. And while there may be some Arguments for that, there is a mysterious story as to why February 14th has become known today as "Valentine's Day." Our story dates back centuries ago, to the Roman Empire, and the martyrdom   of two or three Christians named Valentine. At least one of those Valentines is thought to have been killed on February 14th. Legend has it that this particular Valentine wais killed by a Roman emperor because he secretly presided   over the marriages of young men and women, against the wishes of the Emperor, who wanted only single men to fight in his army. However, there is no historical evidence to back this up. But what is widely known is that the love-element to Valentine's Day can be first traced   to the poetry of Geoffrey Chaucer. Chaucer wrote a poem in 1382 to mark the anniversary of his King's engagement, and scribed a line -- "For this was Saint Valentine's Day, when every bird cometh there to choose his male." From this point, on Valentine's Day became intertwined with love. But for the pessimists out there who see Valentine's Day as a commercial idea, there is some historical evidence to back this up as well! The true popularization   of Valentine's Day can be traced to late 18th century England, when a British publishing company first started selling paper Valentine's Day cards with tender words on them. They became so popular that by the middle of the 19th century, some 1.3 billion British pounds a year were being spent on Valentine's Day gifts. 
 Question: What is this text mainly about? 
 Options: (A) What Valentine's Day means. (B) How Valentine's Day came about/ (C) Why Valentine's Day is so popular. (D) When people created Valentine's Day.

Article: About 6 percent of luxury hotels in three major Chinese cities have stopped serving shark fin ,a survey has found. Although the controversial dish remains on the menu at most hotels, Green Beagle Environment Institute, a Beijing-based non-government organization that was the main sponsor of the survey, said the results are encouraging and reflect increased awareness. The survey was carried out in Beijing, Shenzhen and Fuzhou, which were selected as representative cities to collect basic data on shark fin consumption nationwide. In Beijing, 132 hotels completed the phone questionnaire between Nov. 20 and Dec. 12. Only 12 hotels, 9 percent, said they do not serve shark fin. A similar survey of 131 Beijing hotels conducted a year ago found only one hotel that did not serve shark fin, Wang Xue, chief coordinator of the survey, said on Saturday.In Shenzhen, four out of the 85 four and five star hotels surveyed had stopped serving shark fin, accounting for about 5 percent. In Fuzhou, only one of the 40 hotels surveyed did not serve shark fin. On average, about 6. 61 percent of the hotels in the three cities did not serve the food. "The survey reminded us there is still a long way to go to remove shark fins from Chinese hotels and restaurants, but the improved situation in Beijing is encouraging," said Wang. "We found more hotels and restaurants were willing to take action over the past year." International hotels are more active in the "shark-fin-free" project, she noted. China is the world's biggest importer and consumer of shark fin, which has been used in luxurious Chinese dishes for 500 years. Dishes made from shark fin are still regarded as a symbol of honor and respect,especially at business dinners, according to Wang. Research has also found that shark fin contains poisonous elements, but the nutritious value is less than that of chicken or pork. "We hope hotels and restaurants remove shark fin products from their menus," Wang added.
